The detailed form of the model in [1]} is given in our eqs. (REF ), (REF ). The model has two unconstrained superfields with canonical kinetic terms at \(X=T=0\) . The couplings \(\tilde{\gamma }, \tilde{\zeta }, \tilde{f}, \tilde{g}\)  depend on the renormalization group time \(t= \ln {\Lambda \over \mu }\) . There is a claim in [1]} that in the limit \(t=0\)  their model in the global supersymmetric case is the Volkov-Akulov model, and in the local supersymmetric case it represents supergravity interacting with the nilpotent multiplet. However, this claim is not justified for several reasons:
